The pipe 19 opens into 'the top ofthe head 16 immediately above the cylinder 14, so that the incoming air enters the upper end of the cylinder 14.

VF or the purpose of supporting the device, the headers 16 andv 17 are providedv with stuiiing boxes 21 and 22'adapted to closely fit the exhaust piper 13 and which are adapted to be tightened upon the exhaust pipe for binding the headers thereto and also holdying the headers against the opposite ends of the cylinders 14 and 15. Y* The exhaust pipe 13 thus provides the central portion ofthe cylinder 14, and the latter is provided with a partition wall or `plate23, disposed diametrically and longitudinally in the cylinder 14 and the plate 23 is divided into two portions which lie at opposite sides of the. exhaust pipe 13. The partitionplate 23 fits closely up against the innerside ofthe head .'16, so asoto eectively divide ,the upper end of the cylinder 14 into two distinct compartments. One of these compartments opens `directly into the pipe 19 to'receive theair and the partition plate `23 directsthe air downwardly, and terminates in spaced relation above the 'lower head 17, so that the downwardly moving air is free to .passfupwa-rdly about the lower end of the partition plate 23 and rise in the .cylinder 14 tand at the opposite side of the .termediate partition wall 24, which at opposite sides conforms to the curvature of the adjacentportions of the cylinders 14 and 15,

but which is terminated in spaced relation tothe front wall 25 ofthe head 16 to form a` communicating passage 26 between the cavities of the head1 16,'s`oas to intercommu- I e `nicate the cylinders 14 andf15 at their up- .perends through the head 16.` Theair passing upwardly through the outer side ofthe ,cylinder14 is carried through the passage r26'into the top of the cylinder 15. vThe head y i 16 is provided' with an outlet pipe 27 adapt- `ed forjconnection,withI the carbureter and positioned coupling 26 arranged in the headl manifold 11 vto receive the air from the circultous chamber after it has passed through Hbothof thecylinrders 14 and 15.

f Thepipe 27 opens into a concentrically @-116 above the cylinder 15 'and to which is secured a depending pipe 29.which passes .lfrorn thev diluting lighter downwardly in the cylinder l15 and. is preferably flared or flanged as at 30 at its lower end and in spaced relation to the bottom If desired, the pipe 29 may be equipped upon .its outer surface with a spiral blade 31. This spiral blade 31 directs the air in a spiral path and consequently causes theair to move downward'ly with a whirling action so as not only Y to thoroughly admiX the air, but to throw the heaviest particles ycarried by the air outwardly against the sides of the cylinder 15, and particularly after the air strikes the iiange or flared portion 30. In this manner the heavy particles vcarried by the air are projected downwardly jand outwardly toward the lower end of the cylinder 15, Vso that the Vparticles may be caught inthe conical chamber 32 formed in the lower head 17 beneath the cylinder. 15. The chamber 32is provided with a return pipe y33 for oil or the like which may be carried in the air and which is caught in the chamber 32. YThe pipe 33 enters theflowerportion of the chamber and the latter carries immediately above the pipe a cylindrical screen 34 which supports a deiiecting disc 35 of a diameter less vthan that Vof the inner wall of the chamber 32, so as to provide an annular space or passageabout the discv35 through which the oil or heavy particles may pass for accumulation in the chamber 32.v

vThe head 16 is provided at its intermediate front wall portion with acOnnectingnipple 36 to whichV an oil yfeedingfpipey37 may be attachedfor supplying oilto the passage 26 in they head 16. The nipple36 lmay be pro-k vided with a feed nozzle 38 of any approved type', butwhichin thefpresent li-nstanceris shown Aas projecting across the -passage 27y and provided with an. opening 3,9 at oneside n remote from the cylinder 14,-so that air passingfrom the cylinder 14 throughthe passage 26 has an injectoraction to insure the; feeding' ofthe oil throughthe pipe 37 into the streampof air which flows through jthe passage26-`V j i An important, feature ofthe present in# vention is the` fact that the air .passages through the chamber arefrelatively large,V

so that a great volume'rv of airmay be constantlyl fedk through the device, yand the l'oilpipe 3,7Land its 'nozzle 39 are relatively small, so kthat but a. small volume fof oil'. is fed intofthe largefvolume'of air. 'This insures the more complete breakingup ythe stream of air and the more complete ofthwirin separationfo'fthe heavier particles of the oilk constituents,

which arev readily taken up as a vapor and carrying the diluents strikes `the disc 35 and are deiected upwardly through the pipe 29 and are carried outwardly 'through the pipe 27 to the carbu'reterv and manifold lll The oil entering in the chamber 32 is carried through the screen 34 and pipe 33 back to the crank case of the engine 30, as shown in Figure l.

The oil in the pipe'37 is carried upwardly ktherein by any suitable means and may be connected to the fly wheel housing in the ordinary manner, so that a centrifugal force in the oil is relied upon for feeding it upward'ly through the pipe 37. OfV course,

, when the installations are variedfpumps or other oil -feeding devices well known may be utilized as the present invention is applicable Vto all types of oil feeding systems which arey used with internal combustion engines "of various makes. Y

It .is obvious that various changes Vand modifications may be made in thedetails ofl construction and design of the above specif ically described embodiment of this invention without departing from the spirit thereof, such changes and' modifications being restricted only bythe scope of the following claims. i

What is claimed is 1. That method of removing diluents and other volatile constituents from crank case oil, which consists in passing air' on its wav to theintake manifold of an engine through a heatingchamber, admiXing the heated air in large volume lwith a relatively small volume of the oil and forming the adinixture into a mist, spirally whirling the admixture of air and oil to prolong the contact `of the air and oil and maintain the mist/form whereby the heated air mayreduce the sur-` that the heavy oil is collected lected by 'means Yat the othery end facel tensionV of theoil to Va point Where the diluents are freed from the oil, abruptly reversing the direction of -flow of the admixture of oil and air to separate the heavier from the lighter constituents soL that the air may carry off the lighter constituents there- 'Y I With, and collecting the oil freed of its lighter constituents andreturning the oil to the crank case.

2. A separator for removingdiluentsand other volatile constituents'from )crank case oil, comprising a body 'portion for receiving, air in relatively large amounts by volume f Y and'including a spiral directing element for imparting a whirling motion to the air passing through the body, crank case oil in relatively sniall amounts by volume into said'body portion for a'dmixture with the air to remove the lighter constituwhirling of the admixture, a baffle plate at the endiofsaid spiral element for receiving thel admiXture thereagainst, and means for changing the ture effective adjacent the baffle plate whereby the heavier constituents of the oil are colinomentum upon the baffle plate and the air and lighter constituents are carried olf therefrom and freed from the oil.

3. A separator for removing diluents andv other volatile constituents oil, comprising a heater adapted to receive'a relatively large volume .of air to heat the saine, a centrifugal separator connected to the heater at one end for receiving the air from the heater, means for admittinga relatively small volume of Aoil to said end-of the separator for admixturewith the air,- the air and oil adapted to commingle and vform a'mist in its passagethroughout they lengthjof the? separator Aand the heavier particles of oil adapted to be separated by centrifugal force from the lighter constituents and the air,

direction of flow of the admirl from crank case of said separator forv means for admitting reversing the l'direction of the airand lighter Y y v constituents to separatethe samefromy the heavier constituents of the oil, and-means for collectingv the heavier constituentsof the 100 j f oil at saido'therfend of the separator.
